The occasion marked only the second time the stars have come together, and the first time outside the U.S.

Shatner, who played Captain James T. Kirk, tells the BBC any former rivalry "has long since passed" and the stars are now "good friends", adding, "I would presume getting together is a problem because we live in divergent (sic) areas of the world."

The event hosted Britain's first Klingon wedding for a Swedish bride and groom and also broke the Guinness World Record for the largest gathering of fans dressed in Star Trek costumes.
